When pregnant rats received single intramuscular injections (1, 4, or 16 Units/kg) at three different periods of development (prior to implantation, implantation, or organogenesis), no adverse effects on fetal develop ment were observed. The developmental no-effect level for a single maternal dose in rats (16 Units/kg) is approximately 2 times the human dose of 400 Units, based on Units/k g.
Severe side effects are very rare but can happen if the botulinum toxin unexpectedly spreads throughout the body from the site of the shots. This can cause muscle weakness, hoarseness or trouble talking, trouble saying words clearly, loss of bladder control, trouble breathing, trouble swallowing, double vision, blurred vision and drooping eyelids. The breathing and swallowing problems can be life-threatening. If this happens, seek medical attention right away.
Though botulinum toxin is available under different names, Botox is the only one that is FDA-approved for migraine prevention. To be considered for Botox, patients must have migraines 15 days or more per month, which is considered chronic daily migraine. About 4 million Americans have such migraines, according to the Migraine Research Foundation. Also, patients must have tried and failed on at least 2 other medications first.
So when I first propositioned my husband about the idea of me getting a bit of Botox for the furrowed brow I've earned from a decade of writing and editing behind a computer screen, he was adamantly against it. And frankly, I was a bit scared too. I mean, isn't Botox poison? As an idealistic 21 year old, it was easy to say that I'd never put that stuff in my body, that "poison." Now, I'm not so sure.
Postmarketing safety data from BOTOX and other approved botulinum toxins suggest that botulinum toxin effects may, in some cases, be observed beyond the site of local injection. The symptoms are consistent with the mechanism of action of botulinum toxin and may include asthenia, generalized muscle weakness, diplopia, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence, and breathing difficulties. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulti es can be life threatening and there have been reports of death related to spread of toxin effects. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults treated for spasticity and other conditions, and partic ularly in those patients who have an underlying condition that would predispose them to these symptoms. In unapproved uses, including spasticity in children, and in approved indications, symptoms consistent with spread of toxin effect have been reported at do ses comparable to or lower than doses used to treat cervical dystonia and spasticity. Patients or caregivers should be advised to seek immediate medical care if swallowing, speech or respiratory disorders occur.
Side effects from therapeutic use can be much more varied depending on the location of injection and the dose of toxin injected. In general, side effects from therapeutic use can be more serious than those that arise during cosmetic use. These can arise from paralysis of critical muscle groups and can include arrhythmia, heart attack, and in some cases seizures, respiratory arrest, and death. Additionally, side effects which are common in cosmetic use are also common in therapeutic use, including trouble swallowing, muscle weakness, allergic reactions, and flu-like syndromes.
Exploratory analyses of this study suggested that the majority of patients who had shown a beneficial response by week 6 had returned to their baseline status by 3 months after treatment. Exploratory analyses of subsets by patient sex and age suggest that both sexes receive benefit, although female patients may receive somewhat greater amounts than male patients. There is a consistent trea tmentassociated effect between subsets greater than and less than age 65. There were too few non-Caucasian patients enrolled to draw any conclusions regarding relative efficacy in racial subsets.
Firstly, that is one of the most popular combination of areas for Botox treatment in my office. Like others on this panel, I happen to think the fairest method for charging for Botox is by the unit. Botox can only be purchased through Allergan here in the United States and comes in a 100 unit bottle typically. The only common denominator between offices is how many units of Botox are you...

As the only Facial Plastic Surgeon in North Texas to have Diamond status with Allergan, we have found that in today's economic environment, patients want value as well as quality. Understand that when you go to a non-physician med-spa for injectible treatments, there are more hands in the "cookie jar" diluting the price for your treatment. For example, the med-spa that is owned by a non-physician, with a nurse injector, is the hardest model to stay competitive in today's world. In that scenario, the patient is paying for the cost of the Botox; PLUS the cost of the nurse to inject the product; PLUS the fee for the medical director to sign off on the nurse doing the injections; AND the profit for the medspa. By going to a physician, the patient can cut out 2 of the middle-people. The chances of getting more product for the same price is greater by going to a doctor's office for your treatment.
In some cases known as off-label use, doctors are safely administering it for conditions other than what it is officially approved for, including prostate issues, and eye-crossing (known medically as strabismus) cerebral palsy—which had my jaw on the floor. Rowe even went on to tell me it's the drug of the twenty-first century. "It's like Tylenol or aspirin," he marveled to SELF. "It's what penicillin was in the mid-twentieth century."
With the outbreak of World War II, weaponization of botulinum toxin was investigated at Fort Detrick in Maryland. Carl Lamanna and James Duff developed the concentration and crystallization techniques that Edward J. Schantz used to create the first clinical product. When the Army’s Chemical Corps was disbanded, Schantz moved to the Food Research Institute in Wisconsin, where he manufactured toxin for experimental use and generously provided it to the academic community.
This imbalance can affect a joint in varied ways such as at the ankle with foot position (always points toes or up on toes when walking) or at the wrist with hand position (hand in flexion with problems grasping). After a contracture occurs (not able to bring the joint through its full range of motion, even with forceful / prolonged stretching) it can be hard to re-establish full range of motion at that joint without surgery.
The recommended dilution is 200 Units/2 mL, 200 Units/4 mL, 100 Units/1 mL, or 100 Units/2 mL with preservative-free 0.9% Sodium Chloride Injection, USP, depending on volume and number of injection sites desired to achieve treatment objectives (see Table 1). In general, no more than 50 Units per site should be administered using a sterile needle (e.g., 25-30 gauge) of an appropriate length. Localization of the involved muscles with electromyographic guidance may be useful.
Duration of response was calculated as the number of days between injection and the date of the first visit at which patients returned to 3 or 4 on the HDSS scale. The median duration of response following the first treatment in BOTOX treated patients with either dose was 201 days. Among those who received a second BOTOX injection, the median duration of response was similar to that observed after the first treatment.
Dr. Starling says the FDA approval indicates that the anti-CGRP treatments are ideal for individuals with episodic migraine who have four to 14 headache days per month, and people with chronic migraine who have 15 or more headache days per month. Clinical trials are also being conducted to see if anti-CGRP antibodies are effective for the treatment of cluster headache. “The initial studies have demonstrated that it’s likely effective for cluster headache patients,” Dr. Starling says. The FDA’s approval of these medications has been incredibly meaningful for the migraine community. “The migraine community is feeling like they’re relevant—that they’re being seen, heard and taken seriously,” Dr. Starling says. “There are many people who are working hard to develop more treatment options until we can address every patient who has migraine, and eventually find a cure.”
In general, the initial effect of the injections is seen within three days and reaches a peak at one to two weeks post-treatment. Each treatment lasts approximately three months, following which the procedure can be repeated. At repeat treatment sessions, the dose may be increased up to two-fold if the response from the initial treatment is considered insufficient, usually defined as an effect that does not last longer than two months. However, there appears to be little benefit obtainable from injecting more than 5 Units per site. Some tolerance may be found when BOTOX is used in treating blepharospasm if treatments are given any more frequently than every three months, and is rare to have the effect be permanent.
In a recent Facebook Live, our new director Nim Lalvani introduced herself to the migraine community. If you missed our Facebook Live, watch the recording below or read on to learn more about Lalvani’s personal connection to migraine and her plans for the Foundation.

Lalvani’s background is in public health, and she has dedicated her career to patient engagement. She has worked in the nonprofit and patient advocacy spaces for more than 12 years, helping patients at both the national and international level. “I've specifically focused my career on designing and providing the rights tools and resources for patients at the times that they need it most,” she shared, adding that her goal is to amplify patients’ voices in research and therapeutic development.
Serious and/or immediate hypersensitivity reactions have been reported. These reactions include anaphylaxis, serum sickness, urticaria, soft tissue edema, and dyspnea. If such a reaction occurs, further injection of BOTOX should be discontinued and appropriate medical therapy immediately instituted. One fatal case of anaphylaxis has been reported in which lidocaine was us ed as the diluent, and consequently the causal agent cannot be reliably determined.
Table 14 presents the most frequently reported adverse reactions in a placebo-controlled, double-blind post-approval 52 week study with BOTOX 100 Units (Study NDO-3) conducted in MS patients with urinary incontinence due to detrusor overactivity associated with a neurologic condition. These patients were not adequately managed with at least one anticholinergic agent and not catheterized at baseline. The table below presents the most frequently reported adverse reactions within 12 weeks of injection.
Focal Spasticity is a condition in which certain muscles in your body become stiff or tight. It is caused by damage to parts of the central nervous system that control voluntary movements. When this happens, your nerves send continuous messages to your muscles telling them to contract, or tighten. If you or someone you care for has stiffness in the muscles of the elbow, wrist, fingers, thumb, ankle, or toes, it could be Focal Spasticity.1
